A fish theme optimized for people who use:

• Solarized
• Git
• Mercurial (requires 'hg prompt')
• SVN
• Unicode-compatible fonts and terminals (Use a Powerline patched font, e.g., from here: https://github.com/powerline/fonts)
• Fish Vi-mode

For Mac users, I highly recommend iTerm 2 + Solarized Dark

Characteristics

• If the previous command failed (✘)
• If private mode is enabled (🔒)
• User @ Hostname (if user is not DEFAULT_USER, which can be set in your profile)
• Git status
• Subversion status enabled by adding set -g theme_svn_prompt_enabled yes to your config.fish.
• Mercurial status enabled by adding set -g theme_mercurial_prompt_enabled yes to your config.fish.
• Branch () or detached head (➦)
• Current branch / SHA1 in detached head state
  • Current branch name is shortened to 15 characters by default. Change it to N characters with set -g fish_vcs_branch_name_length N in your config.fish.
• Dirty working directory (±, color change)
  • By default, git repos will show as dirty if there are untracked files. This can be changed by adding set -g fish_git_prompt_untracked_files no to your config.fish. This value is passed into git status --untracked-files, so any value git supports is valid for this command
• Current working directory
• Elevated (root) privileges (⚡)
• Current virtual environment (Python virtualenv and Nix Shell) You will probably want to disable the default virtualenv prompt. Add to your init.fish: set -gx VIRTUAL_ENV_DISABLE_PROMPT 1
• Indicate vi mode.
• Source control blacklist. To disable source control prompts in certain directories, you can add the following to your init.fish or config.fish: set -g scm_prompt_blacklist "/path/to/blacklist".
• The icons can be configured by setting variables. E.g. to replace the icon of failed command from the default "✘" use set -g glyph_status_nonzero "💀". For configuration options see fish_prompt.fish.
